Bonding characteristics of Rajasthan Bentonite from M/s. Tata Locomotive & Engineering Company Ltd. Tatanagar

This investigation on the bonding characteristics of a Rajasthan bentonite was referred to National Metallurgical Laboratory by M/s. Tata Locomotive & Engineering Co.Ltd., Tatanagar. A 30 lb. sample of the bentonite was supplied by the above firm in the form of lumps 2 to 3” in size. As received, the bentonite sample was pale yellowish in colour and contained 7-7. 5% moisture.
